CONTROLLING MEANS FOR TAKE-UPS FOR LOOMS.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed April 29, 1907. Serial No. 370,852.

To all whom it may concern:

Be it known that I, MARTIN MoUL, a citizen of the United States,residing at Hanover, county of York, and State of Pennsylvania, haveinvented certain new and useful Improvements in Controlling Means forTake-Ups for Looms, of which the following is a specification.

My invention relates to controlling means for takeups for looms.

The present invention has for its object the provision of a novelautomatic clutch shifting mechanism for use with the take-up mechanismof looms, particularly those used in weaving wire fabrics, its functionbeing to automatically shift the clutch controlling the take-up windingroll according to the movement of the tension mechanism so that thetake-up roll will be antomatically started or stopped according toconditions of operation.

The invention is set forth fully hereinafter and its novel features arerecited in the appended claims.

In the accompanying drawings:Figure 1 is a side elevation; Fig. 2, anend elevation, partly in section, and Fig. 3, a detail perspective ofthe rocker arms and drop-weight.

Only so much of a wire loom is shown as will enable the presentinvention to be fully understood.

The loom frame 1 has pivoted thereto at 2 arms 3 (only one of which isshown) which support the tension roll 4. A weighted lever 5, pivoted toframe 1 at 6 and resting on a lug 7 on arm 3, completes the tensionmechanism. The take-up winding roll 8 is journaled in frame 1 andcarries a worm-wheel 9 which meshes with and is driven by a worm 10carried by a shaft 11 having a clutch part 12 fixed thereto. A driveshaft 13, which revolves continuously, has loosely splined thereto at 14a clutch part 15 which revolves with the shaft 13 but is capable ofbeing shifted into or out of engagement with clutch part 12 by a yoke 16which is secured to a shaft 17 journaled in frame 1.

Secured rigidly to shaft 17 is a rocker having the arms 18 and 19provided, respectively, with the fingers 20 and 21. Loosely mounted onshaft 17 is a dropweight 22 which is adapted to play between the fingers20 and 21 and, by its engagement with them, rock the shaft 17 one way orthe other. Loosely mounted on the shaft 17 and located next thedrop'weight 22 is a rocker having the arms 23 and 24 provided,respectively, with fingers 25 and 26 adapted to be made to engageopposite sides of the drop-weight 22 to shift it one way or the other. Ared 27 connects the arm 24 to the lever 5. Secured to shaft 17 is an arm28 to which a hand-lever 29 is fastened at 30, said hand-lever extendingto the front of the machine in convenient reach of the operator. A link31, pivoted to the lever 29, has a pin-and-slot connection 32 with thelever 5 permitting said lever 5 to play up and down to normal limitswithout shifting said link.

While requirements of operation are being satisfactorily fulfilled, theclutch parts 12 and 15 are engaged and the take-up roll 8 is in rotationbut if the tension becomes too great the lifting of the weighted lever 5causes rod 27 to rock the double-rocker 23-24 sufiiciently to cause arm24 to engage and lift drop-Weight 22 beyond its position of equilibriumand it then drops by gravity to the position shown by full lines,carrying with it the double-rocker 1819 and rocking the shaft 17,thereby disengaging the clutch parts 12 and 15. When the tensiondecreases, the dropping of the lever 5 causes rocker arm 23 to engagewith and return the drop-weight to its former position during whichmovement the drop-weight carries the rocker 1819 with it, thus turningshaft 17 back to its former position and reengaging the clutch members12 and 15, causing rotation of the takeup roll.

In case the lever 5 fails to act, the operator may use the hand lever 29to control the rotation of the take-up roll by shifting the clutch. Thelink 31 also serves to shift the clutch in case the drop weight fails toact.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:-

1. In a controlling means for loom take-ups, the combination with amovable tension mechanism, and a clutch for controlling the take-up, ofa clutch shifter, a dropweight shifter, an operative connection betweenthe movable tension mechanism and the drop-weight shifter, and adrop-weight mounted loosely in relation to the drop-weight shifter forloose movement in relation thereto which is adapted to cooperate withthe clutch shifter.

2. In a controlling means for loom take-ups, the combination with amovable tension mechanism, and a clutch for controlling the take-up, ofa clutch-shifter, a pivoted drop-weight adapted to cooperate with theclutch-shifter, a double rocker having arms adapted to engage thedropweight to move it in opposite directions, and an operativeconnection between the movable tension mechanism'and the double rocker.

3. In a controlling means for loom take-ups, the combination with amovable tension mechanism, and a clutch for controlling the takeup, of arock-shaft having an operative connection with the clutch, adouble'armed rocker secured to the rocleshaft, a drop-weight pivotallymounted on the rock-shaft and adapted to play between and engage thearms of the rocker aforesaid, a drop-weight shifter, and an operativeconnection between the dropweight shifter and the movable tensionmechanism.

4. In a controlling means for loom take-ups, the combination with amovable tension mechanism, and a clutch for controlling the takemp, of arock-shaft having an operative connection with the clutch, adoublenrnled rocker secured to the rock-shaft, a drop-weight pivotallymounted on the rock-shaft and adapted to play between and engage thearms of the rocker aforesaid, a dropweight shifter, a doublehrmed rockerloosely mounted on the shaft whose arms lie on opposite sides of and areadapted to engage the drop-weight, and :in operative connection 10between the lust named double rocker and the movable tension mechanism.

In testimony whereof, I hereunto nihx my signature in presence of twowitnesses.
